BAND-CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No. 519,211, dated May 1,1894.

Application fiIedMay 1.1898. SerlalNo. 472.549. on model.)

To aZZ whom it may concern:

Be it known that we, WILLIAM SEBINE VAN WECHEL and Banners LoUIs WYNIA,both of Orange City,in the county of Sioux and State of Iowa, haveinvented a new and Improved Band-Cutter and Feeder, of which the follow-I ing is a full, clear, and exact description.

Qur invention relates to improvements in band cutters and feeders, suchas are used in connection with thrashing machines to out I the bands ofbundles of grain and to feed the guiding the bundles, to the end thatthey may come, in a proper manner, in contact with the band cutters, toprovide means for adjusting the machine to feed different sizes ofbundles, and in general to produce a machine of the kind described,which will do the work required of it in a very effective manner andwill not easily get out of repair. I

. To these ends our invention consists of certam features ofconstruction and combina-f tions of parts, as will be hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figuresof reference indicatecorresponding parts in all the views.

band cutter and feeder, to a thrashing machine. Fig. 2 is a plan View ofthe same. Fig. 3 is ahorizontal section on the line 3-3 in Fig. 2; andFig. 4 is a front end View of the apparatus.

The thrashing machine is of the usual kind, having the customary beatingcylinder 11 and secured to the thrashing machine near the cylinder, isthe usual separator frame 12 which generally carries the feed boards andtables, but these are removed when our im- Bolted to the outer end ofthe separator frame 12 are upwardly-extending castings 12 which formaframe to support the cutters, cutter guards, and certain pulleys ashereinafter described. Extending through the frame 12 is a carrier 13,and this carrier is mounted in a vertically swinging framel and uponrollers 15 and 16, these being arranged in the usual way at the endsofthe carrier. The carrier has theusual center board 17, and consists ofan endless belt 18 with the usual cross slats, this running over therollers 15 and 16. The roller 16 is arranged at the inner end of thecarrier, is adapted to slide horizontally in-a slot19 at the lower endof the hood above the frame 12*, and this arrangement enables thecarrier to be moved in and out and facilitates also its verticallyswinging motion. The inner roller 16 has at one end a driving pulley 20which connects by means of a belt 21 with a pulley 22 on the cuttershaft 23, this extending transversely across the frame 12 and above thecarrier 13, the shaft being provided with suitable band cutters, as willbe hereinafter described. The shaft 23 is also provided with a pulley24- which is driven by a belt 25 connecting with a pulley 26 on thecylinder shaft, and this shaft may be turned in any usual way.

The outer end of the carrier frame 1 1 is provided with a suitablesupport 27 which is pivoted thereto and is adapted to be turned up tosupport the guide bar as hereinafter described. The carrier 13 is heldnormally in the machine andwith the roller 16 at the inner end of theslot 19, byaspiral spring 28,

which is secured to the carrier and to the Figure 1 is a side elevationof the improved showing it applied frame 12. The carrier may be raisedwhen necessary by means of a cable 29 which extends through the frame14: and upward over guide pulleys 30 on.the frame 12, the ends of thecable being secured to a crank shaft or Windlass 31 which is journaledin supports on the top of the thrashing machine or in a convenientplace, and the shafthas a crank or handle 32 at one end by which it maybe turned.

The carrier is drawn out bymeans of a cable 33 which is secured to theinner end of provements are applied to the machine. the carrier andextends outward over guide roe pulleys 34 on the frame 12 and thendownward to a Windlass or shaft 35, which is journaled in suitablesupports beneath the frame 12, and is provided with a crank 36 by whichit may be turned. It will be observed that the winding of the cable 29upon the shaft 31 shortens the cable and lifts the outer end of thecarrier 13 and that the winding of thecable 33 on the shaft 35 forcesthe carrier out-- ward, so that by properly manipulating the two shaftsthe carrier may be held at any necessary pitch.

Behind the cutter shaft and above the inner end of the main carrier 13is a second carrier or feed apron 37, which is placed at an angle to themain carrier and extends inward and downward beyond the inner end of themain carrier. The feed apron 37 is carried by rollers 38 and 39 and isprovided 011 its face with projecting hooks 38 which incline toward theouter end of the feed apron. The shaft of the upper roller 38 is held inslots 40 in the hood, which supports the feed apron and which will bedescribed presently, and both the rollers are journaled in a swingingframe 41, the lower end of which rests upon a stud 42, see Fig. 3, whichprevents the frame and feed apron from dropping too low. The apron andframe may, however, swing freely upward and in this way the apron adaptsitself to the varying bulk of the bundles, which are fed into themachine, and it is thus prevented from choking and is still able toaccomplish its work, as described below. The shaft of roller 38,carrying the upper end of the feed apron, is provided with a pulleywhich is driven by a belt connecting with a pulley on the shaft 23. Whenthe parts are in operation the proximate surfaces of the feed apron andcarrier travel in the same direction, but

the feed apron is arranged to travel slower than the carrier.

The feed apron is supported in a swinging hood 44 which closes the rearportion of the machine, and which swings over the cylinder 11, this hoodbeing hinged at its rear end, as shown at 45, to the frame of thethrashing machine. It will be seen then that the hood and the feed apronmaybe swung upward, as shown by dotted lines in Fig. 3, thus entirelyexposing the cylinder 11, so that it may be easily reached if necessary,and by swinging up the carrier 13, in the manner previously described,the lower portion of the cylinder may be easily reached.

The cutter shaft 23 is provided with revoluble band cutters, ofsubstantially the usual kind, these comprising oppositely projectingblades 46 which turn a little above the carrier 13 and which passthrough the bundles and sever the bands. Adjacent to the cutters are theguards 47 which hang from a cross bar 48 above the cutters, and these attheir lower ends are curved beneath the shaft 23 and between the cutters46, their lower portions 49 extending rearwardly substantially parallelwith the carrier 13, as shown clearly in Fig. 3. The guards prevent thestraw from Winding around the cutter shaftand choking the cutters.

Above the carrier 13 and near its free end, is a guide bar 50 whichextends longitudinally and the outer end of which comes into closecontact with the carrier. This baris pivoted on a supporting bracket arm52 which is fastened to the top of the frame 12, and consequently theguide bar may swing when the carrier is raised. The outer end of theguide bar terminates in an edge 51, as shown in Fig. 2, and is supportedin the end of the upturned support 27. This guide bar acts to separatethe bundles which are delivered to the carrier so that they may besupplied evenly to the band cutters.

The operation of the machine is as follows: The bundles are pitched uponthe carrier 13 and are carried into the machine, the bands being cut bythe revolving cutter blades 46 and the grain is delivered from theinnerend of the carrier upon the cylinder 11. As the grain in the cut bundlesstrikes the feed apron 37 the said apron is raised, and as the feedapron travels slower than the carrier, the hooks 38 on the apron holdback the upper portions of the bundles of grain and allow the lowerportion of the bundle to travel first into the cylinder. Each bundle isthus separated and a continuous and even sheet of unthrashed grain isdelivered to the beater. If the bundles are very large, the lower end ofthe feed apron swings upward under the increased pressure and the aprontherefore adjusts itself to such bundles, while if the bundles arerelatively small, the apron drops down and continues to separate them asspecified. For large bundles, the outer end of the carrier 13 is droppedinto a relatively low position, thus making a comparatively large spacebetween the carrier 13 and the cutters and permitting the bundles tofeed freely, while if the bundles are smaller, the outer end of thecarrier is raised so as to bring its carrying surface nearer thecutters.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination with a thrashing machinehaving the usual cylinder, of a sliding pose set forth.

2. The combination with a thrashing machine having the usual cylinderand provided with a sliding and vertically swinging carrier adapted todeliver to the cylinder, and a feed apron arranged above said carrier,of a hood held above the inner end of the carrier and above the cylinderand carrying said feed apron, said hood having a longitudinal slot atitslower edge to admit of the horizontal movement of the carrier and havinga hinged connection at its rear end to theframe of the thrasher, wherebythe hood and feed apron may be swung upward when necessary and thecylinder exposed, substantially as shown and described. 1 l l t 3. Thecombination in a band cutter and feeder, with the revoluble bandcutters, of the carrier arranged to move beneath the cutters, thebracket arm fastened to the frame above the cutters,t-he guide barpivoted to said bracket arm in front of the cutters and extendinglongitudinally above the carrier apron, the supporting arm pivoted tothe'outer j end of the carrier frame and adapted to be turned upward tosupport the free endof the guide bar when in position over the carrier,substantially as shown and described,

be swung vertically and moved longitudh nally, substantially asdescribed.
